Programming and Debugging
The lp_em_cc2340r5 board supports the runners and associated west commands listed below.
| flash | debug | debugserver | rtt | attach | |
|---|---|---|---|---|---|
| jlink | ✅ (default) | ✅ (default) | ✅ | ✅ | ✅ |
The LP_EM_CC2340R5 requires an external debug probe such as the LP-XDS110 or LP-XDS110ET.
Alternativly a J-Link could be used on the J4 header, in combination with a 3.3V power supply over the pinheader. Debugging and flashing is currently only tested using a J-Link on the J4 header.
To get a console, connect an external USB to UART converter with:
TX |
DIO22 |
RX |
DIO20 |
Then you can connect to it from you PC:
$ microcom -p <tty_device>
Replace <tty_device> with the port of your USB to UART converter.
For example, /dev/ttyUSB0.
Flashing
Applications for the CC2340R5 LaunchPad board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b lp_em_cc2340r5 samples/hello_world
west flash
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b lp_em_cc2340r5 samples/hello_world
west debug
